Do you use Ansible roles to provision your infrastructure? And would you like
to use those very same roles to create container images? You came to the right
place!

We are working on a project (and you problably heard of it already) called
Ansible Container. It’s not
just about creation of container images. It covers the complete workflow of
a containerized application. From build, local run, test to deploy.

In this blog post, I would like to show you how Ansible Container does those
builds — from an Ansible role to a container image.

I was playing with epoll and was curious whether I can use it to monitor
sys.stdin. The biggest issue was that sys.stdin.read() is blocking and I
had no way to figure out whether I read the descriptor fully or not (making the
epoll useless pretty much). Until I changed it to non-blocking with fcntl.

After my yesterday talk at DevConf 2016 I got asked about some tips and tricks how to write Dockerfiles. I know we have plenty of resources for that in Red Hat, Fedora and Project Atomic. So, here we go!
